Embodiments described herein include methods, systems, and apparatuses for allowing a user equipment (UE) that supports dynamic spectrum sharing (DSS) with uplink (UL)-shift to access a cell and barring UEs that do not support DSS with UL-shift. Embodiments may use a cell barring field in a master information block and additional filters to indicate a barring state for a network node.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The method of claim 1, further comprising checking that the UE supports UL-shift only for an initial bandwidth part (BWP) against a particular sub-carrier spacing (SCS) the initial BWP is configured with, and wherein the UE accesses the cell when the UE supports UL-shift for the initial BWP.
3. The method of claim 1, further comprising checking that the UE supports UL shift for all the BWPs against a SCS broadcasted information provides, and wherein the UE accesses the cell only when the UE supports UL-shift for all BWPs.
4. The method of claim 1, wherein the first message is a master information block (MIB) and the second message is a system information block 1 (SIB1).
5. The method of claim 1, wherein the second field is provided in a FrequencyInfoUL information element.
6. The method of claim 1, further comprising reporting to the network node UL-shifting capability for each band that the UE supports.
8. The UE of claim 7, wherein the instructions further configure the baseband processing unit to check that the UE supports UL-shift only for an initial bandwidth part (BWP) against a particular sub-carrier spacing (SCS) the initial BWP is configured with, and wherein the UE accesses the cell when the UE supports UL-shift for the initial BWP.
9. The UE of claim 7, wherein the instructions further configure the baseband processing unit to check that the UE supports UL shift for all the BWPs against a SCS broadcasted information provides, and wherein the UE accesses the cell only when the UE supports UL-shift for all BWPs.
10. The UE of claim 7, wherein the first message is a master information block (MIB) and the second message is a system information block 1 (SIB1).
11. The UE of claim 7, wherein the second field is provided in a FrequencyInfoUL information element.
12. The UE of claim 7, wherein the instructions further configure the baseband processing unit to report to the network node UL-shifting capability for each band that the UE supports.
14. The non-transitory computer-readable storage medium of claim 13, wherein the computer-readable instructions are configured to instruct the one or more processors to check that the UE supports UL-shift only for an initial bandwidth part (BWP) against a particular sub-carrier spacing (SCS) the initial BWP is configured with, and wherein the UE accesses the cell when the UE supports UL-shift for the initial BWP.
